1、下载Firebird3.0安装包到Linux系统文件下，并解压该文件，进入解压后的文件夹执行 ./install
2、会遇到报错Please install required library ‘libtommath’ before firebird, after it repeat firebird install，根据提示需要先安装依赖libtommath
# (1). 安装 EPEL 仓库（如果需要）sudo yum install-y epel-release# (2). 安装 libtommathsudo yum install-y libtommath-devel
(3)再次执行./install.sh，成功安装输入密码后完成安装但会提示警告，
gsec工具不能加载库libtommath.so.0
/opt/firebird/bin/gsec: error while loading shared libraries: libtommath.so.0: cannot open shared object file: No such file or directory
# （1）. 查找系统中已安装的 libtommathsudo find/usr-name"libtommath*"2>/dev/null#（2）创建符号链接找到的是 libtommath.so.1sudo ln-s/usr/lib64/libtommath.so.1/usr/lib/libtommath.so.0
3、再次执行./gsec,会提示报错缺少依赖 libncurses.so.5:
./gsec: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory
# （1） 安装 ncurses5 兼容库sudo yum install-y ncurses-compat-libs
4、至此顺利初步安装完成Firebird3.0服务
